FASTENING DEVICE Filed May 21, 1932 ATTORN EY Patented Aug. 2, 1932UNITED STATES PATENT OFFICE ADOLF BUSCHHAUS, OF WUPPERTAL-BARMEN,GERMANY, ASSIGNOB TO BARTHE-LS MANUFACTURING COMPANY, OF GLENDALE, NEWYORK, A CORPORATION OF NEW YORK FASTENING DEVICE Application filed. May21, 1932, Serial No. 612,830, and in Germany February 11, 1930.

This invention relates to fastening devices which are adapted for usewith elastic cords, elastic bands and the like, and such fasteningdevices are preferably in the nature of 6 couplings for the oppositeends of such cords or bands, which are thereby preferably made endlessin effect, and which may therefore be used with stockings, underwear andother wearing apparel by drawing them or rolling them thereinto so thatthey serve as means for holding such articles of apparel in desiredwearing position.

An object of the present invention is to provide a fastening device ofsuch a construction that an end of an elastic cord or band willautomatically tighten itself therein when properly applied thereto.

Another object of the invention is to provide a fastening device withpinching portions which are spaced away from the body or plate whichsupports them, for a distance less than the thickness of the elasticcord, elastic band, etc., whereby to promote the automatic tightening orsecurement of the end of the cord or band.

Another object of the invention is to provide fastening devices of theclass referred to, which are of very simple construction and yetexceedingly satisfactory and efficient when in use.

These being among the objects of the present invention, the sameconsists of certain features of construction and combinations of partsto be hereinafter described and then claimed with reference to theaccompanying drawing illustrating two embodiments of the invention andwherein Fig. 1 is a plan of the preferred form, an elastic cord beingindicated in broken lines;

Fig. 2 is a side elevation thereof;

Fig. 3 is a cross-section on the line 3-3, Fig. 1; and

Fig. 4 is an edge elevation of one end of the fastener.

Referring to the drawing, the preferred construction of such fasteningdevice comprises a main body 10 which is preferably composed of sheetmetal so that such body is in the form of a plate, which is preferably50 elongated and provided at the end edges with body so that they willbe directed the one towards the other.-

In some cases one of the tongues 11, 11a might be omitted and replacedby some other securing means, and when two tongues are employed they areboth preferably located opposite one face of the body or plate 10.Vhether one or two tongues are employed, each tongue is provided at itsinner end with an inwardly turned or bent end portion 12 which serves asmeans for spacing the main body of the tongue away from the plate 10.Each tongue is provided with a slit 13 whereby opposite side portions ofthe tongue are spaced away from each other for a slight distance.Preferably this slit 13 is narrower towards the connecting end of thetongue than towards its inner end. such slit extending into the outerbend of the tongue as well as into the inturned end portion 12. so as toenable the introduction thereinto of one end of an elastic cord or band.The ends of the slit 13 are terminated by an enlarged opening 14 in theinturned end portion 12 and an-enlarged' opening 15 in the connectingbent por tion between the main body of the tongue and the plate 10. Aportion 16 of the tongue remains between the opening 14 and the terminalof the tongue, thereby forming a slight connecting bridge. In thedrawing the device is shown larger than. in practice. as in practice thefastening device is used for securing the end of a comparatively smallelastic cord or band. Preferably the proportions of the parts of thefastener are such that the distance between the edges at opposite sidesof the slit 13 is less towards the base or connecting portion of thetongue than towards the inner end of the tongue. with the result thatthe material of the end of the cord which is inserted into the slit ispinched towards the outer end of the slit, because such end of the slitis of less transverse dimension than that i pull the cord or band so asto stretch and narrow the same, thereby enabling its introductionlaterally into the slit 13, and then on releasing such other hand fromthe cord or band, the latter will resume its unstretched condition andautomatically tighten itself within the-slit, the convergingedges of thetongue portions at opposite sides of the slit acting automatically topinch some ofthe material. of thecord or band and secure the latter inplace. Theend ofthe cordlor band when applied is pressed down into theenlarged openings 14, 15, and inasniuchza'szeach tongue 11, 11a isspaced also a less distance from the plate or body than the thicknessofthe elastic cord or band, the holding effect is augmented when the cordis released and p allowed to resume its unstretched condition.

In both. of the illustrated forms of the invention itiis obvious thatthe tightening of the ends of the elastic cord or band may befacilitated by inclining the tongues silghtly towards the plate or bodyso that the distance from the same decreases toward the narrowed ends ofthe slits, inasmuch as the end of the cord willbe' pressed closely inbetween the tongue and'plate or body. In Fig. 1, two end portions 17 18of a cord are shown in broken lines as connected by the device.

It is obvious that the inventionis susceptible to more or lessmodification as will .be obvious to those skilled in this particularart.

\Vhat is claimed as new is,.

A fasteningdevice oft'he class described, comprising a inetallic bodyhaving a. tongue bent back from an edge. of the body and spaced awayfrom such body, the inner end of the tongue being bent inwardly towardsthe body, such tongue having a longitudinal slit, and also liavingenlarged openings in tlie'p'ortion at such edge andlin the'i'nwardlybent end, which openings are connected by such slit.
